Diseases of the nose and throat; a text-book for students and practitioners . .—Transverse-Vertical Section through Posterior Portions of Okkits,Looking Forward. (From a photograph.) Eye. Ethmoid cells. Antro-nasal opening. Antrum of Highmore. Inferior turbinate!. Roof of nal meatusMiddle Inferior palate. Key to Fig. 1. CHAPTER I. Anatomy of the Nose. The nasal passages may be designated double begin at the anterior nares (nostrils), pass through ahighly vascular, nervous, and tortuous region, and terminate inthe posterior nares (choanse). These tunnels are separated,antero-posteriorly and vertically, by the nasal septum, which ispartially cartilaginous, but chiefly bony. The nasal passagesare narrow above and quite broad below. The septal walls aresmooth, but, owing to the presence of the turbinated bodies,the external walls are very irregular. Connected with thesecanals are several accessory cavities, which often participate inpathological changes similar to those which occur in the nasalfossae The septum narium is about one-tenth of an inch thickanteriorly and one-eighth posteriorly. It is formed above bythe perpendicular plate of the ethmoid bone, post
